What are the difference in terms of effect of different types of Vitamin A or its derviative.
I know Vitamin A in skin care products has antiaging effect. Its derivative includes:
Retinyl Palmitate,
Retinol
Retinaldehyde
Retionic Acid
Some people does have skin allergy with Vitamin A products, which of those derviative will have less chance of getting skin allergy and is more easy to absorb and its effective in anti-aging. |
